A subcontractor working in an electrical closet at Kenmore West High School died in an accident early Wednesday morning, a school district official said.
The district has not identified the worker or the company for which he worked.
The incident happened prior to 7:30 a.m. as electrical work was being performed as part of the school district's capital project, said Patrick Fanelli, community relations coordinator for the Kenmore-Town of Tonawanda School District.
Teachers returned to the high school on Tuesday, but no students were in the building at the time because they are still on summer break, Fanelli said.
The worker had been doing work in the electrical closet – a central hub for electrical services for the school – which is off-limits to staff and students, he said.
"Our hearts and thoughts of staff are with the worker's family and friends, and our sincerest sympathies are extended to all those affected by this loss," the Ken-Ton district said in a statement. "The district is fully cooperating with the investigation of this matter and remains committed to ensuring that work on district property is performed safely and in accordance with all applicable workplace standards."
Occupational Safety and Health Administration (OSHA) was notified and investigators from the federal agency were on the scene Wednesday morning, according to the district.
